摘要： To provide sliding components each comprising a base metal and, joined thereto, a sliding face member having a sliding face of crowning profile, in particular, sliding components such as valve train parts, a cam follower and a rocker arm of an automobile engine. A sliding component having a structure comprising (1) a ceramic forming a sliding face and (2) a base metal joined together, in which the extent of crowning of the sliding face is at least 0.1 to 0.4% of the maximum length of the junction face of the ceramic. The ceramic has a four-point flexural strength of at least 50 Kg/mm as measured in accordance with the Japanese Industrial Standard R1601. The base metal is mainly steel at least the surface of which has preferably a martensite texture and has a hardness of higher than 45 in terms of H.sub.RC. The structure may have an intermediate layer of a metal or cermet. In one mode the junction of the sliding face member such as a ceramic of crowning profile is simultaneously carried out with the formation of the base metal part and in another mode the sliding face of the base metal is hardened by the heating after the junction. A sliding component whose extent of crowning is great can be provided at a lowered cost without suffering from defects such as cracking.

摘要： The present invention is intended to provide a sliding member that can prevent abnormal wear and partial wear of the mating metal sliding component even when an oil contaminated with exhaust gas components is used. A ceramic sliding component is manufactured as followed. A silicon nitride-based material for the sliding face member is joined to a metal body having a higher thermal expansion coefficient than the sliding face member. A crowned portion is formed on the sliding face of the sliding face member in such a way that the difference between the amounts of crowning (da, db) at two arbitrary points axially symmetric with respect to the center line of the crowned portion is 10% or more and 50% or less of the average of the crowning amounts at the two points.

摘要： A silicon nitride ceramic sliding member which includes Si.sub.3 N.sub.4 grains as a main component and is shaped or controlled in dimensions through hot plastic working wherein the Si.sub.3 N.sub.4 particles mainly includes .beta.-type columnar crystal grains. The ceramic sliding member is produced by the step (I) of preparing a preform made of silicon nitride ceramic sintered body including Si.sub.3 N.sub.4 grains as a main component wherein the average grain size (average grain size in minor axis in the case of .beta.-type columnar crystal grains) of the Si.sub.3 N.sub.4 grains is at most 0.5 .mu.m, and the hot plastic working step (II) of placing the preform in a mold and effecting hot plastic deformation of the preform for shaping or dimensional control thereof while simultaneously increasing the average aspect ratio of the .beta.-type columnar crystal grains. The resultant sliding member has excellent sliding properties, a high mechanical strength and a high reliability at a low cost without resort to grinding or the like for shaping thereof.

摘要： First and second sliding parts of a sliding mechanism slide relative to each other. The first sliding part is held in a recess of a metal holding member, which is bounded by an inner wall that meets an open end of the recess along an edge. The first sliding part has a first side surface portion that contacts the inner wall in the recess away from the edge, and a second side surface portion displaced inwardly away from the inner wall so as not to contact the holding member at the edge. By this structure, generation of stress concentration on the sliding part can be avoided.

摘要： An industrially feasible method of grinding silicon nitride ceramics, is disclosed and provides a sufficiently smooth surface. Namely, the surface has a maximum height-roughness Rmax of 0.1 microns or less and a ten-point mean roughness Rz of 0.05 microns. Further, with this method, surface damage can be repaired while grinding. The vertical cutting feed rate of a grinding wheel into a workpiece should be within the range of 0.005-0.1 micron for each rotation of the working surface of the wheel and change linearly or stepwise. The cutting speed of the grinding wheel in a horizontal (rotational) direction should be within the range of 25 to 75 m/sec. With this arrangement, the contact pressure and grinding heat that is generated between the workpiece and the hard abrasive grains during grinding are combined. In other words, mechanical and thermal actions are combined.

摘要： A combination of an adjusting shim and a cam used in a valve train in an internal combustion engine for automobiles, the adjusting shim composed of a ceramic material which sets the surface roughness of a sliding surface of the adjusting shim with respect to a cam to not more than 0.1 .mu.m in ten-point mean roughness Rz, and which contains not less than 60 vol. % of silicon nitride or sialon, and the cam composed of cast iron a surface of which is chill hardened and then provided with a phosphate film thereon. The combination of an adjusting shim and a cam is capable of smoothing a sliding surface of the cam by the break-in of the part even if the cam is not subjected to a super-precision finishing process; preventing the seizure and abnormal abrasion of sliding surfaces; stabilizing a smoothed condition of the sliding surfaces of the cam and shim for a long period of time; and providing excellent sliding characteristics of the sliding surfaces owing to a decrease in the friction coefficient thereof.
